Iris Duct Dampers - Air Controls

Galvanized airflow regulator, specifically designed for circular ducts with nylon gear mechanism and rubber gasket on in- and outlet. Two manometer connections measure the differential pressure with a chart to calculate the values on either side whereby the removable key opens the blades.

It is recommended to install the damper at minimum twice the diameter from T connection or from outlet, and at minimum once the diameter from curves and inserted in ducts by 30mm each side for dia 200mm and inferior and by 40mm for the two larger sizes. Use in temperature -10°C to +80°C.

TDE

The Multiflow TDE 500 to 710 range consist of fully cased, cylindrical models with circular mounting flanges at both ends and a wired terminal box.

RVF

The Mini Centrifugal Roof Fan series are the new type roof extract units available in 2 sizes and suitable for vertical and horizontal installation. The low noise external motor and high efficient backward bladed impeller meets the requirement of efficient ventilation in residential, commercial and light industrial applications.

Future 150

The Decor Series can be wall or ceiling mounted and is designed to exhaust stale and moist air from bathrooms, toilets, laundries etc. They are also suitable for ventilating all types of small or closed areas.

TD Silent

The Silent Series is a low profile mixed-flow in-line fan that produces low noise when in operation. It does this through a specifically designed perforated internal skin that directs sound waves produced inside the fan to a layer of sound absorbent material.

TD-Evo

NEW!! TD-EVO

The low-profile TD-EVO 250 and 315 in-line mixed-flow fans for circular ducts have a unique design where the support bracket allows the motor and impeller assembly to be fitted or removed without dismantling the adjacent ducting.
